Two self-styled privacy hawks in Congress have turned their attention toward Apple, asking the company for answers about how it is collecting and using information about its users’ geographical location.

In a letter to Apple (NASDAQ: AAPL) CEO Steve Jobs, Reps. Ed Markey (D-Mass) and Joe Barton (R-Texas) posed a string of questions about a recent addition to the company’s privacy policy that staked a broad claim to information associated with users’ location: “Apple and our partners and licensees may collect, use, and share precise location data, including the real-time geographic location of your Apple computer or device,” the policy now reads.

That didn’t sit well with Markey and Barton, who sent the letter (available in PDF format here) to Jobs in response to a report in the L.A. Times highlighting Apple’s policy change.
